DETAILED DESCRIPTION

Reference is now made to several views of the drawings in FIGS. 1-15 to show an embodiment of the combative helmet of the present invention. The basic helmet construction is shown at 10 and a visor is shown at 12. Typically, part of the helmet construction includes a padded rim 13 illustrated in FIG. 1. FIG. 1 also illustrates the slide assembly at 20. Although not illustrated in the drawings, there is a like mirror image slide assembly 20 on the opposite side of the visor so that the same pivoting action can occur on both sides of the visor.

The fragmentary perspective view of FIG. 3 illustrates the slide assembly 20 in what may be considered a locked position. Reference can also now be made to FIG. 12 which shows the basic components of the slide assembly 20. This slide assembly 20 includes a main base plate 22 that is secured to the helmet. This is illustrated in FIG. 3 secured to a wall 14 of the helmet 10. The base plate 22 has end internally threaded holes 23, a sawtooth interlock surface 26, a hole 25 for accommodating screw 50 and a tang 27 (see also FIGS. 4 and 5). The slide assembly also includes the slide plate 30 which includes an elongated slot 31 for receiving the screw 50 and a sawtooth surface 32. The slide plate 30 is also provided with internally threaded holes 34. In FIG. 12 a third main component is the pivot plate 40. The screw 50 is secured to the pivot plate 40 by means of a pin 54. The screw 50 has a threaded end at 55 and a head 51 with a hole 52 extending therethrough. The pin 54 is for accommodation in a set of holes 46 in respective arms 44 of the pivot plate 40. The pin 54 is positioned through the holes 46 and provides a pivot point for the pin 50.

FIGS. 4 and 5 illustrate main base plate 22 secured to the helmet wall 14. This securing of the base plate 22 firmly holds the base plate against the wall 14 by means of screws 24. FIGS. 4 and 5 also illustrate the screws 36 used for attachment of the slide plate 30 with the visor 12. As also illustrated in FIGS. 4, 5 and 12, there is another through hole 25 that accommodates the screw 50 that is free-floating within the hole 25. The hole 25 may be un-threaded. The base plate 22 also includes an end tang 27. In FIG. 4 this end tang 27 is shown engaged by the latch 42 at the end hook 43. FIG. 4 shows the engaged position, while FIG. 5 illustrates the latch 42 having been disengaged from the tang 27. This enables a pivoting of the pivot plate 40. This pivoting is illustrated in an initial position in FIG. 5, and is generally about the axis of the pin 50.

Reference is now made to FIGS. 6-10 which show the following operation that enables the visor to be moved forwardly and pivoted upwardly. In this regard, FIGS. 6 and 7 illustrate a relationship between base plate 22 and the slide plate 30 that is interlocked. In that regard, the respective sawtooth surfaces 26 and 32 are shown interlocked in FIG. 7. FIG. 7 also illustrates by arrow 70 the pivoting of the pivot plate 40 to a position substantially orthogonal to the base plate 22. In the position of FIG. 7, the screw 50 is engaged within the hole 25 of the base plate 22.

Reference may now be made to the cross-sectional view of FIG. 8 which illustrates a de-coupling between the sawtooth surfaces 26 and 32 to enable a sliding action of the slide plate 30. This occurs by virtue of the wearer of the helmet moving the slide plate away from the base plate, such as in the direction of arrows 72 as illustrated in FIG. 8. This sliding motion occurs while the pin 50 is still maintained in the hole 25 of the base plate 22. FIG. 9 now illustrates the next step which is the sliding of the slide plate 30 in the direction of arrow 74. This is enabled by virtue of the elongated slot 31 in the slide plate 30 that enables the slide plate to move to the position of FIG. 9 while still engaged with the pin 50. Finally, in the fragmentary enlarged perspective view of FIG. 10, the arrow 76 illustrates a pivoting of the visor to an upward position. In the position of FIG. 10, the end 47 of the pivot plate 40 at arms 44 is preferably flat so that the pivot plate 40 is essentially maintained in that position while still allowing a pivoting action in the direction of arrow 76. FIG. 11 also illustrates this pivoting action, illustrating the slide plate 30 and the pivot plate 40.

Reference is also now made to respective side elevation views shown in FIGS. 13-15. The purpose of these views is to illustrate the manner in which the visor 12 can easily be moved forwardly and then pivoted upwardly so as to clear the cushion 13 on the helmet 10. In this regard, FIG. 13 illustrates a visor wall 15. It is noted that in the closed locked position of the visor, this wall 15 is under the cushion 13 and thus would not be able to be moved upwardly. The next side elevation view of FIG. 14 illustrates the slide member 30 being moved in the direction of arrow 80. In that position it can be seen that the visor wall 15 is clear of the arcuate cushion member 13. Finally, in the side elevation view of FIG. 15, the arrow 82 illustrates a pivoting or tilting of the visor 12 to an open position. The pivoting of FIG. 15 is essentially about the axis of the screw 50.

It is also understood that the actions described herein can readily be reversed so that the visor can be moved from the open position as illustrated in FIG. 15 to a downward position as illustrated in FIG. 14 and from there the slide member is slid in the direction opposite to the arrow 80 in FIG. 14. The sawtooth surfaces 26 and 32 can then be engaged as illustrated in the cross-sectional view of FIG. 7 and the pivot plate 40 is then pivoted to a locked position as illustrated in the cross-sectional view of FIG. 4.

As indicated previously, there is a slide assembly 20 on each side of the helmet and the actions that are described herein are meant to apply equally to both the slide assemblies so that the action taken is in concert, whether opening or closing the visor.
